clients/audio/audio_object.cpp calls spa_pod_find_prop() but only includes <spa/pod/parser.h>. Newer pipewire headers no longer pull iter.h in transitively, so the declaration is missing.

Building with GCC 16.2.0 and pipewire 1.4.x fails with:

clients/audio/audio_object.cpp: In function 'const spa_pod_prop* cutefish::audio::AudioObject::getProp(const char*)':
clients/audio/audio_object.cpp:34:34: error: 'spa_pod_find_prop' was not declared in this scope
   34 |     const spa_pod_prop* prop = spa_pod_find_prop(object, nullptr, key);
    |                                  ^~~~~~~~~~~
clients/audio/audio_object.cpp:34:34: note: suggested alternative: 'spa_pod_for_each_prop'

Including <spa/pod/iter.h> explicitly fixes it.

Thanks for the fix! I reproduced the error by building against the pipewire 1.6.0 spa headers, and with this change audio_object.cpp compiles.

clients/audio/tests/fake_audio_device.h has the same problem: it calls spa_pod_find_prop(), spa_pod_copy_array() and spa_pod_get_bool() with only <spa/pod/parser.h>, so -DBUILD_TESTING=ON still fails. No need to update the PR, I'll add the include there myself.
